y = -3
x = 5(-3)
x = -15
(-15, -3)

5x + 4(-7x - 3) = -35
5x -28x -12 = -35

25A2B is a 5-digit number. If the number is divisible by 5 and 9, find all the possible values of A and B. Explain also.
3241004551 [841]

Answer:

25020, 25920, 25425

Step-by-step explanation:

To find if our number is divisible by 5 the number must end with 0 or 5, divisibility by 9 is if sum of all numbers in number is divisible by 9,

We know B must end with 0 or 5

1. Case 25A20 sum of that number is 9 so if we pick 0 as A we have first number because 9/9=1

We can put A as 9 because 18/9=2

2. Case B = 0, sum is 14 so we need pick A as 4 to get 18.

A bad contains 8 black,3red and 9 white balls. If 3 balls are drawn at random, find the probability that none is red
LenKa [72]

Argument

You have a total of 8 + 9 + 3 balls = 20

The first ball is 17/20         Probability that no ball drawn is red the first time

The Second ball is 16/19   Probability that no ball drawn is red the 2nd time

The third ball is 15/18        Probability that no ball drawn is red the 3rd time

Answer

Total Probability = 17/20 * 16/19 * 15/18 = 34/57

My calculator figures out fractions. You can do this just as easily with decimals.

0.85 * 0.8421 * 0.8333333 = 0.5964

34/57 = 0.5965  which is close enough.

If you have choices, choose the one that coincides with my answer. Otherwise use the decimal value.
